--- Comment #4 from medin <med.medin.2...@gmail.com> --- After trying many things, it seems the culprit is that blur effect, disabling it seems to fix the slowness and the mouse cursor regains its smoothness, but I get a transparent confirmation layer which is not looking good. Is there any way to apply a simple solid color to that layer instead of blurring the whole screen? -- You are receiving this mail because: You are watching all bug changes.
